A young boy and his mother live in a future in which the wealthy exchange their flesh and blood bodies for immortal android bodies.
The natural humans are hunted for sport. The movie begins with the young
boy and his mother hiking through a snowstorm to get to the spaceport/train station to leave the planet in search of an off world site to get themselves android bodies.
They are being stalked by a hunting party.

I remember just few things unfortunately.
There was something like ice kingdom. Something like that. Robots were slaves? Maybe. They keep watch. They had to wear shoes. I think that kids really escaped. Kids found some castle with queen...that is it.
